What Are the Different Types of PBX System?

Let’s take a closer look at the different types of PBX system.

When you are looking to upgrade your phone system for your company, you’ll need to consider the various PBX systems and which one is best suited for your business. PBX stands for private branch exchange, and in simplest terms, it provides a phone system suitable for businesses to accomplish their day to day voice communication needs. The ability to reach specific extensions, intercom, initiate conference calls, assign customers to wait for assistance, and provide background music for those customers are all distinct features of a business PBX system. Let’s take a closer look at the different types of PBX system. 

Digital PBX System

The digital PBX system is designed to be expandable in terms of the features they boast and what your business can accomplish with them. A digital PBX system can accommodate a traditional analog PBX system, as well as IP (Internet Protocol) phones. Then you can choose to upgrade your digital PBX system by adding in background music for customers on hold, and integration with VoIP systems. Compared to an analog system – which is typically a simple solution for a home-based business – digital PBX systems deliver better sound quality. These systems also offer the standard functions like extensions and transfers, but they also offer digital answering assistants, voicemail, and the ever-useful call-forwarding feature.  

On-Site IP PBX System  

Unlike their digital counterparts, on-site IP PBX systems (also known as VoIP PBX systems) take full advantage of existing bandwidth and robust internet connections that are readily available.  With the explosion of VoIP phone service and unified communications, the Internet Protocol platform is now regarded as the most commonly-seen type of PBX system.

On-site IP phone systems utilize your business’s internal networks – and since they use the Internet, on-site IP PBX systems can deliver greater call stability, better sound quality, and more advanced applications of a PBX system. Some of these features include interfacing with other elements of your company’s unified communications – like voicemail to email, mobility integration and video calling. For an on-site VoIP PBX system to reach its full potential, you will likely need to use SIP trunking. SIP trunking provides additional benefits such as disaster recovery, call accounting, advanced call routing, and can even save 40% – 75% on your calling services.

Virtual PBX System

A virtual PBX system, also known as a Cloud PBX or Hosted PBX, provides all PBX system features, applications, and calling services in the cloud. The Virtual phone system, applications, features and phone service are billed monthly under one invoice.  And since your telecom service provider “hosts” your virtual phone system, ongoing software updates, PBX maintenance, and warranties are no longer your concern.  Other benefits of cloud-based phone systems include multi-office networking, advanced disaster recovery, and budget-friendly pricing.
